Pediatric Morbidity Among Black Haitians in Canada: A Longitudinal Cohort Study

In the U.S., Black children have disproportionately elevated rates of pediatric morbidity compared with White children, but data are lacking for other countries. We studied the extent to which Black Haitians were at risk of pediatric morbidity in Canada.

We analyzed a retrospective cohort of 736,498 children born in Quebec between 2008 and 2020. We identified Black Haitians using the mother tongue and birth country of parents. The outcome was mortality or hospitalization for infectious diseases, allergy, cancer, and other morbidity between birth and 12 years of age. We estimated hazard ratios (HR) and 95% confidence intervals (CI) for these outcomes, comparing Haitians with non-Haitians in Cox regression models adjusted for patient characteristics.

Compared with non-Haitians, Haitians tended to have a greater risk of pediatric mortality, especially before age 2 years (HR 1.56, 95% CI 1.00–2.45). However, Haitian children had a lower risk of hospitalization than non-Haitian children (HR 0.61, 95% CI 0.59–0.63). Haitians were less likely to be hospitalized for infectious diseases, allergies, appendicitis, cancers, fractures, dental caries, and ophthalmologic conditions. Hospitalization rates were low throughout childhood, even though Haitian children were more likely to be born preterm, develop severe neonatal morbidity, and have other adverse outcomes at birth.

Haitian children have an elevated risk of neonatal morbidity and early childhood mortality, but lower risk of hospitalization compared with non-Haitians in Canada. The reasons for the disparity are unclear, but greater effort is needed to address potential gaps in healthcare among Black children.
